I think I may go with this torque converter.

Thanks for the advice. I've got to do what's in my budget.

BTR recommends 2500-3k stall. Id try to hit in in the middle. If you're towing, stay on the lower end because of heat. Also, it will depend on the gear, if you change it. More converter for lower gear. Also, you can grab a 278mm for less rotating mass. I wouldn't recommend going with the 278 if you're towing alot. Smaller converter, less fluid, more heat. If you don't have an external trans cooler, you'll probably need to add one. My avalanche got up to 214 climbing the mountain coming home from work in knoxville in the hottest part of the summer. Thats with 26-2800.

We've used the "cyclone" brand remans (stock) and never had an issue. I say this because we typically buy them from Trans Star (Formerly Dacco in Cookeville) but the last one we did, my buddy ordered that "cyclone" brand on eBay and it shipped from trans star and was the same converter we had been getting for years. It wasn't orange either, if you're into those kinda things.

"The Stage 3 grind is a popular choice for those looking to delete DOD/AFM, or just add some pep to your trucks step. With great power gains and driving characteristics, this camshaft works well with a 2500-3000 stall torque converter."

This is everything that I upgraded to when I did my cam--

What break in oil do you guys use or should I just fill it with the castrol edge 5w30 and just change it at 500 miles. Then so on and so forth?

 

[thingraylinetah]

I have to do what's in my budget. So all I can afford is the cyclone torque converter.

Cheapest conventional you can find. I think I usually drive it a little, 25 miles or so and change it. Then go 500 and do it again. I usually buy whatever oil change special autozone or whatever has. If they don't have one, some super tech CONVENTIONAL and delco filter.

I didn't know if they offered higher stall speed for that same price or not. That's why I mentioned the stall speed specifically, not the brand.

 

[thingraylinetah]

I'm not sure I'm about ask and find out.

 

[thingraylinetah]

It says on the paperwork to use Rotella 15w40 for break in with Delco filter. Then drain that and use royal purple 10w30 for 500 miles.

 

[pwtr02ss]

I would follow what they recommend.

 

[thingraylinetah]

I guess after the 500 miles I can drain the royal purple and then start running castrol 5w30 synthetic with wix extended performance filter

 

[thingraylinetah]

I guess if I'm going to upgrade the torque converter then I'm going to also upgrade the sun shell, install the corvette servo, and the sonnax super good 4th gear servo, also I think I might have a raybestos zpak installed.

So my wife bought me this torque converter for my birthday.

I don't recommend the zpak for heavy trucks or SUV. Just replace with borg heavy duty frictions and while you're in there, replace the accumulator pistons with the sonnax pinless, and do the wide band on 2nd gear.
The issue with the zpak on the heavy trucks is the fact that you're losing steel thickness to get more frictions in that pack. Thinner steels means less heat absorbing and therefore faster warping. I like the borg heavy duty frictions over raybestos heavy duty because they soak up the fluid better (my own personal testing). Also, gm uses borg frictions from the factory.

Everybody is quoting at least 1k to put just the motor alone in. I'm scared to check and see the price on the transmission upgrades.

I'm not sure what local shops charge to do those things but the parts are really not that expensive. I imagine you're not inclined to do the work yourself? I can send you a really good video that goes over tear down and assembly. You have to buy some specialty tools that would probably eat up any savings from diy

 

[thingraylinetah]

Are you a mechanic?

 

[thingraylinetah]

Not inclined

 

[thingraylinetah]

My stepson is going to ask the dude he works for how much it'd be to do all the work.
